I strongly recommend Choon Fei's place mainly for its very convenient location. In general, Soi 18 is one of my favorite, way less hectic than others, with large sidewalks, breezy and shaded, few steps from Terminal 21 & BTS Asok; the apartment is right in front of Coffee Club and at 2 steps from great Thai restaurants. I had food at palm@18 probably 10 times in a week, so delicious. Other than that, the studio is like shown in pictures, good value for money, very good wifi, good communication with host and easy check-in.
